Note. YBOCS = Yale-Brown Obsessive Compulsive Scale; PEAS = Patient EX/RP Adherence Scale; PEAS_A = percentage of assigned HW exposures that were attempted, PEAS_B = quality of attempted exposures; PEAS_C = degree of success with response prevention. CI = confidence interval; sr² = squared semipartial correlation, a measure of the unique variance explained by each predictor that is equivalent to the R² change in a hierarchical model when each predictor is entered previously.
